The Hellier paranormal documentary series began with 2012 reports of small creatures harassing a family in Kentucky, mirroring the Hopkinsville case. Geologically, the Sloan Valley Cave System in Pulaski County connects to the Mammoth Cave System, providing a subterranean link between disparate sighting locations. Investigators frequently find three-toed footprints at these sites, suggesting a recurring biological or paranormal entity.

Greg and Dana Newkirk of the Hellier series visited Somerset to investigate similar claims of child-killing cults and "green men." Their findings overlapped with Nathan Isaac's research, revealing that multiple women in the area were reporting nearly identical ritualistic trauma. This intersection caused the Pennyroyal production team to temporarily halt their work due to the potential danger of interfering in active criminal matters.
